Laptop is Overheating
Laptop becomes abnormally hot after and during use
Faulty Ventilation Fan
Ensure that there is nothing blocking the airflow of the ventilation fan/system surrounding the laptop. If the area around the laptop is clear, clean any debris on the ventilation ports on the underside of the laptop using an air-duster. Air-duster can be purchased at most hardware stores, however you must be 18 or older to purchase the item. If the laptop continues to overheat after cleaning the ventilation fan area, consider purchasing and replacing the faulty fan.

If there is nothing wrong with the charging cable, consider replacing the power jack to fix issue.
